Salve a tutti. Ho provato a fare dell'anfetamina con questa ricetta su piccola scala, ma non ci sono riuscito. Sembrava tutto a posto, dopo l'essiccazione il mio prodotto si presentava come una polvere bianca con una punta di rossore. Se si trattasse di anfetamina solfato (che stavo cercando di produrre), la resa sarebbe dell'84%. Il problema è che non si tratta di anfetamina.

Effetti fisiologici
Ho provato 20-30 mg, c'è stata sicuramente una stimolazione, ma ha anche causato febbre e, apparentemente, un calo delle difese immunitarie: entrambe le volte che l'ho presa per diversi giorni di seguito, mi sono ammalato di infezioni respiratorie (la prima volta ho pensato che fosse una coincidenza). Un'altra persona che l'ha preso non ha avvertito alcuno stimolo fino a 90 mg, ma solo un po' di secchezza della bocca. Nessuno dei due ha una tolleranza agli stimolanti.

Test chimici
1 g di polvere si scioglie completamente in 10 ml di H2O.
Quando ho aggiunto un eccesso di soluzione di NaOH a una massa misurata di polvere in una provetta, ho ottenuto un volume approssimativo di base libera che odorava di ammoniaca. Ho separato lo strato di freebase, l'ho asciugato con CaCl2 e ho provato a titolarlo con un acido. Come risultato, ho misurato la massa molare della freebase a circa 171 (mentre per l'anfetamina è 135). Anche se le mie misurazioni non erano molto precise, la differenza è comunque troppo grande per essere spiegata solo da errori di misurazione.

Le mie deviazioni dalla procedura

1) Quando ho aggiunto il P2NP, mi sono reso conto che ci sarebbero volute ore, quindi mi sono spazientito e ho immerso la beuta di reazione in un bagno d'acqua a temperatura ambiente. In seguito ho potuto aggiungere il P2NP quasi tutto in una volta e la temperatura della miscela non ha superato i 40-50 °С.
2) Seguendo il video, non ho fatto evaporare l'IPA e ho aggiunto direttamente acido solforico conc. allo strato di IPA/freebase.
3) Non avevo acetone al momento, quindi non l'ho aggiunto prima di acidificare e ho lavato la pasta filtrata di "solfato di anfetamina" con IPA.
4) L'IPA è meno volatile dell'acetone, quindi ho dovuto mettere il mio precipitato in un forno per diverse ore per farlo asciugare a peso costante. La temperatura del forno non ha superato gli 80° C.

Quindi, la domanda principale è: dove è andato storto? Non mi sorprenderebbe una bassa resa o l'assenza di prodotto, ma ottenere una buona resa di un'ammina che non sia anfetamina?!

The method as described here lacks all product workup/cleanup and and as such provides a very dirty and unclean Amphetamine, in special as NasBH4 reductions are all not giving very clean product. Purple MDMA and such.
I know the physiological effects like fever like very well and it is just the missing cleaning trust me.
There are several ways to do the workup, from distillation, normal, vacuum or steam of the base or dissolving the sulfate in water and washing this several times with toluene or petrolether or my favorite: 50/50 mix of petrol ether and Ethylacetate. Then evaporate the water and wash the resulting salt with copious amounts of Acetone and petrol ether as last. Already the simple washings give you a consumable product which does not make you sick like the crap which contains borate salts or else.

Even with the dirtiest amp he would have felt it just fine....guaranteed he got "almost amp" mainly riddled with hydroxylamine. This reaction goes south on people all the time. They have wayyyy too much nabh4 left when it's time to add the copper and with the heat the nanoparticles aggregate and become completely useless as a catalyst....fully useless... and leave semi reduced product. The only way I've been able to get around that is by reducing 1st in methanol/thf to propane then extracting and then using anyone of the zinc/formic acid combos.... for the nitro. Zero Michael addition.

I tried it today, but something must have gone wrong..I followed the instructions exactly, but in the end there is more than there should be. What could have happened? Can anyone give me advice? Can it be cleaned? Thank you for every answer

Please. How do I have a reaction more nabh4? I threw in for 6 hours but still not much nabh4 dissolved. In the end, when I added acid, the whole thing thickened after filtration, a white substance remained, but I suppose it's nabh4.. I followed the instructions I don't know what's wrong.

My mescaline guide might help for 1 or 2 mol amounts. Possibly up to 500 g+ in a 20 L reaction vessel.

The same procedure for P2NP as with Mescaline nitrostyrene, however I do not know if it is more reactive. Have not worked with it.

Take a look here:

Or posted here (if starting from benzaldehyde):

My friend and I always cooked amphetamine in the forest.
That is, for synthesis we really only needed 3 construction basins, Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons that show the reaction.

My role was always bring and serve, but we produced this product of 99.8% purity.
We had no competition in Moscow :/

we didn't use fucking acetone because it's bad for your health

What is the salt of amphetamine present on this photos?

At one point in Russia, they suddenly cut off the liquid propen supply—left a bunch of wannabe cooks totally clueless. Product turned out nasty as hell, colors ranging from sketchy pinks to filthy yellows and straight-up horrifying oranges. But my homie was different—he was one of the few who knew the synthesis inside and out. Back in the day, he cooked pristine pervitin for the whole block, but dude got busted—hit him with a solid 20-year stretch. Luckily there’s a war poppin' off, so he'll probably get tossed onto the front lines and bounce back home early. Then we'll pick right back up where we left off.

but you say "...3 construction basins, Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons..." and in your list of reagents only hydrochloric acid

I can hit him up and get the full cook recipe—it's fuckin' one-of-a-kind.

in this synthesis using only this reagents "...Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons..." amp sulfate cannot be obtained.

with hydrochloric acid obtain amp hydrochloride
with sulphuric acid obtain amp sulphate

Your reagents list remind different synthesis way (Al/Hg approach). Why did you write this post under NaBH4 method? It's, also, interesting about HCl and sulphate salt.
